Description

An Injection Mold Convenient for Embedding Iron Parts

technical field

The utility model relates to the field of injection molds, in particular to an injection mold which facilitates embedding of iron parts.

Background technique

Injection molding is a process for producing parts made of thermoplastic or thermoset plastics. Injection molding is to heat and melt plastic (usually pellets) in the barrel of the injection molding machine. When it is in a flowing state, under the pressure of the plunger or screw, the molten plastic is compressed and moved forward, and then passes through the barrel. The nozzle in the front section is injected into the closed mold with low temperature at a very fast speed. After cooling and shaping for a certain period of time, the mold is opened to obtain the product. The injection molding method is a batch operation process, which consists of two main parts: an injection unit and a clamping unit, the mold in the injection machine can be fixed in a horizontal or vertical position, and the material can be cooled and solidified in the mold (cavity) into the shape of the product. Plastic injection molds are usually made of metals such as steel or iron, and the desired shape of the part is formed by a precision machined cavity.

Injection molding is widely used to manufacture various parts, most of which are plastic products. With the improvement of production technology, the requirements for product appearance and production efficiency are also increasing. Due to the limitation of product structure and appearance requirements of common molds, it is slow to place iron parts in the process of embedding iron parts in injection molds, resulting in long production cycle and unreachable output.
